Tremendously fun… is binutils keeping a broken libopcodes?
Ok, if it helps, I seem to be experiencing this problem only with when binutils has been compiled with USE="multitarget". I'm going to CC in toolchain because of the verified link to binutils (and dotnet, who should've been CCed in from the beginning)...
you need to link in libiberty when linking against libopcodes, and libopcodes also needs libbfd. not really a bug in binutils.
Created attachment 202005 [details, diff] 020_all_system-libbfd.patch with libiberty dep for libopcodes Ok, getting closer. I've discovered it really is only for mono-debugger-2.4.2-r1, because it's in patches-1 provided with it. 020_all_system-libbfd.patch adds in an AC_CHECK_LIB on opcodes. I've tried adding an additional libraries option to the end of the AC_CHECK_LIB call containing just libiberty.la, and that seems to work, but then I can't understand why libiberty wouldn't need adding the bfdlibs variable as well (since it uses -lopcodes)? There were no errors compiling, but I've no idea when mono-debugger will try and call the disassemble symbol it's using from libopcodes. Also I thought mono-debugger built it's own internal copy of libopcodes, and we don't seem to be using the system version of that, so does the system version of libopcodes ever actually get used?...
Mike is there anything different when using multitarget, with these libraries? For what I can see, by default just linking -lopcodes is fine (it has no undefined symbols that are not already taken care of by the NEEDED entries, no libiberty needed), with multitarget that's not true anymore, that sounds like a bug in binutils to me.
some targets use more of libiberty than others, so some targets may not require symbols from libiberty
Hm okay; shouldn't it then link in libiberty by itself at that point, though?
it does already: $ grep iberty /usr/x86_64-pc-linux-gnu/lib/libopcodes.la dependency_libs=' -liberty' if you dont like with libtool, then it's your problem to make sure to pull in all the libs you need
Looks like http://sourceware.org/bugzilla/show_bug.cgi?id=6937 Was fixed in the last patch attached to http://sourceware.org/bugzilla/show_bug.cgi?id=6768 I notice all 2.19.51.0.* versions of binutils have the patch. Backport?
This is still happening on an upgrade of 2.4.2 to 2.6: configure: error: Missing libopcodes library My binutils is configured as: sys-devel/binutils-2.18-r3 USE="multitarget nls -multislot -test -vanilla"
(In reply to comment #12) > I notice all 2.19.51.0.* versions of binutils have the patch Upgrading to binutils-2.20 makes mdb compile and run fine.

(In reply to comment #14) > (In reply to comment #12) > > I notice all 2.19.51.0.* versions of binutils have the patch > Upgrading to binutils-2.20 makes mdb compile and run fine. Once I ~amd64'ed binutils mdb did indeed compile. Can we not just add a >=binutils-2.20 dependency to the ebuild?
no. multiple versions of binutils can be installed.
the referenced upstream reports are a different bug and have no bearing on this one ... i still dont see any indication that this is a bug in binutils. mono-debugger needs to link with -liberty when it tries to use -lopcodes ...
This was the closest bug I could find, but in my case I don't have multilib enabled on binutils, and I can't even get past configure, unless I changed a single line in files/mono-debugger-2.6-system-bfd.patch + AC_CHECK_LIB([opcodes], [init_disassemble_info], [:], [AC_MSG_ERROR([Missing libopcodes library])]) into + AC_CHECK_LIB([opcodes], [init_disassemble_info], [:], [AC_MSG_ERROR([Missing libopcodes library])], [-lbfd]) This is with: binutils-2.18-r3 (nls -multislot -multitarget -test -vanilla) gcc-4.3.4 (fortran mudflap nls nptl openmp -altivec -bootstrap -build -doc -fixed-point -gcj -gtk -hardened -libffi -multilib -multislot -n32 -n64 -nocxx -nopie -objc -objc++ -objc-gc -test -vanilla)
Looks fixed (at least, I am unable to reproduce) with: sys-devel/binutils-2.20.1-r1 (with multitarget USE flag enabled) dev-util/mono-debugger-2.6.3
